I want to get a text(Multi-line) from Edittext same as given Screenshot.
I want below output when getText() from Edittext.
Output:
Lorem Ipsum is simply dummy
text of the printing and
typesetting industry. Lorem
Ipsum has been the industry
standard dummy text.
I have tried below solution but, it doesn't work
etMessage.getText().toString().replaceAll("\\n", "<br />")
By default all the EditText widgets in Android are multi-lined. And you can configure the number of lines and the characters types. By setting the input type to multiline do the trick.
<EditText
...
android:inputType="textMultiLine" <!-- Multiline input -->
...
android:lines="8" <!-- Total Lines prior display -->
android:minLines="6" <!-- Minimum lines -->
android:gravity="top|left" <!-- Cursor Position -->
android:maxLines="10" <!-- Maximum Lines -->
android:layout_height="wrap_content" <!-- Height determined by content -->
android:layout_width="match_parent" <!-- Fill entire width -->
android:scrollbars="vertical" <!-- Vertical Scroll Bar -->
/>
After too much searching and waiting for an answer to this question. I have resolved this issue.
Solution:
I have measured each and every line & words for preserve this as Multiline text, you can use below function for that.
DisplayMetrics metrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
float density = metrics.density;
String result = fitString(ipText, ipText.getText().toString());
private String fitString(EditText editText, String message) {
Log.i(TAG, "fitString: Default String : " + message);

For next comers, I find the accepted answer overcomplicated for the task. Here is a nice extension code in Kotlin that uses Paint.breakText(). That said, it can probably be simplified further...
fun EditText.getMultilineText(): String {
val maxWidth = (width - paddingLeft - paddingRight).toFloat()
val original = text.toString().trim()
val len = original.length
val multiline = mutableListOf<String>()
var p = 0
var count = -1
while (count != 0) {
count = paint.breakText(original, p, len, true, maxWidth, null)
if (p + count < len) {
var tmp = count
while (tmp > 0 && original[p + tmp - 1] != ' ') {
tmp -= 1
}
if (tmp > 0) {
count = tmp
}
}
val tmp = original.substring(p, p + count).trim()
if (tmp.isNotBlank()) {
multiline.add(tmp)
}
p += count
}
return multiline.joinToString("\r\n")
}
did you try this one
message = etMessage.getText().toString().replaceAll("\\n", "<br />")
please see this also How can I preserve line breaks from EditText?
I'm trying to create an app that shows some questions and EditText fields in front of the each of the question for an answer with CountDownTimer, the problem I have is I'm trying to stop the running CountDownTimer on the last entered answer and save those seconds next to user's name but not sure how? I know questionTimer.cancel() would stop the timer but it has to be done on the last entered answer in last EditText.
This is the MainActivity.java file:
public class MainActivity extends AppCompatActivity {
CountDownTimer questionTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnStart = (Button) findViewById(R.id.start);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setQuestions();
timer();
}
});
}//End of create()
public void timer() {
questionTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
timer = (TextView) findViewById(R.id.timer);
timer.setText("Seconds Remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
timer.setText("Done!");
}
}.start();
}
public void setQuestions() {
ArrayList<Questions> qArrList = new ArrayList<>();
for (int i = 0; i < 5; i++) {
ques = new Questions();
ques.setQuestion("");
qArrList.add(ques);

I have manged to sort this out by setting an int variable against Position and calling this in MainActivity class inside the running Timer. Please see the code below.

Your application is sticking when you're scrolling down because you're doing all of that processing upon every move when you scroll. Every row is running through the statements of your getView method every single time it's brought back to the screen, phones don't have enough processing power for all of that. You need to separate all of that into a different class, and then load it into the adapter in a smaller data set so that all it has to do is display it. Basically, you're doing processing in the UI(Main) thread, which is bad.
Given how you also have nested listViews, changing to an expandedListView would also be a lot easier for you in the grand scheme of things, may do the job better. Here's a tutorial for it: https://www.youtube.com/watch?v=BkazaAeeW1Q

for (int i = 0; i < obj.length(); i++) {
try {
JSONObject item = obj.getJSONObject(i);
int itemId = item.getInt("skuId ");
if (itemId == skuId) {// object already exists update quantity
item.put("quantity", qty);
// update other keys if you want to
// do other stuff
return;
}
} catch (JSONException e) {
e.printStackTrace();
}
}
JSONObject jsonObject = new JSONObject();
// If skudId does not exits in the array list add new one
try {
jsonObject.put("skuId", skuId);
jsonObject.put("quantity", qty);
jsonObject.put("productId", productId);
jsonObject.put("price", price);
jsonObject.put("productName", productName);
jsonObject.put("description", description);
obj.put(jsonObject);
editor.putString("data", obj.toString());
editor.commit();
} catch (JSONException e) {
e.printStackTrace();
}
I want to do the replication between Android sqlite & MS SQL server.That Time i want to take Tables values from Databse.
This is my JSON
{
"Table1":[
{
"BusinessUnit":"MASS",
"ProductCode":"SLD0201",
"Description":"Lou Difan C.Blue 12"3- Commode",
"Description2":"301 0201"
},
{
"BusinessUnit":"MASS",
"ProductCode":"SLN0502",
"Description":"Lou Napoli I"vory- Cistern",
"Description2":"2011 0502"
},
{
"BusinessUnit":"MASS",
"ProductCode":"LDMBL6H",
"Description":"Dortek Taper Bullet Handle 6"5 serr ",
"Description2":"Taper Bullet Ha"
}
],
"Table2":[
{
"chk":6,
"currentchk":1
}
]
}
In Here JSON Description column value contain "(double quotation) .If we check http://jsonformatter.curiousconcept.com/ , it show error.Its a Invalid JSON.
WCF service I have converted DataSet to JSON. Some table column contain special charters.
I converted like this :
public String ConverTableToJson(DataSet dsDownloadJson,int currentSplit)
{
StringBuilder Sb = new StringBuilder();
String result = "";
int start = 0;
int end =500;
int chk = 0;
int currentChk = currentSplit;
if (dsDownloadJson.Tables.Count > 0)
{
Sb.Append("{");
foreach (DataTable dt in dsDownloadJson.Tables)
{
DataTable dtDownloadJson = dt;
string[] StrDc = new string[dtDownloadJson.Columns.Count];
string HeadStr = string.Empty;
double total = dtDownloadJson.Rows.Count;
Console.WriteLine("--1--" + dtDownloadJson.Rows.Count);
if (dtDownloadJson.Rows.Count < 500)
{
end = dtDownloadJson.Rows.Count;
}
if (chk == 0)
{
if (dtDownloadJson.Rows.Count > 500)
{
if ((dtDownloadJson.Rows.Count / 500) == 0)
{
chk = dtDownloadJson.Rows.Count / 500;
}
else
{
chk = dtDownloadJson.Rows.Count / 500 + 1;
}
}
else
{
chk = 1;
}
currentChk = 1;
}
else
{
currentChk = currentChk + 1;
start = currentChk * 500;
end = start + 500;
currentChk = chk;
}
Sb.Append("\"" + dtDownloadJson.TableName + "1\" : [");
if (dtDownloadJson.Rows.Count > 0)
{
for (int i = 0; i < dtDownloadJson.Columns.Count; i++)
{
StrDc[i] = dtDownloadJson.Columns[i].Caption;
HeadStr += "\"" + StrDc[i] + "\" : \"" + StrDc[i] + i.ToString() + "¾" + "\",";
}
if (HeadStr.Length > 0)
{
HeadStr = HeadStr.Substring(0, HeadStr.Length - 1);
Console.WriteLine("--2--" + start);
Console.WriteLine("--3--" + end);
for (int i = start; i < end; i++)
{
string TempStr = HeadStr;
Sb.Append("{");
for (int j = 0; j < dtDownloadJson.Columns.Count; j++)
{
TempStr = TempStr.Replace(dtDownloadJson.Columns[j] + j.ToString() + "¾", dtDownloadJson.Rows[i][j].ToString());
TempStr = TempStr.Replace(""", '\"');
}
Sb.Append(TempStr + "},");
}
Sb = new StringBuilder(Sb.ToString().Substring(0, Sb.ToString().Length - 1));
}
}
else
{
}
Sb.Append("],");
if (chk > 1)
{
Sb.Append("\"Table2\": [{\"chk\": " + chk + ", \"currentchk\": " + currentChk + " }]");
}
else
{
Sb.Append("\"Table2\": [{\"chk\": " + chk + ", \"currentchk\": " + currentChk + " }]");
}
}
// Sb = new StringBuilder(Sb.ToString().Substring(0, Sb.ToString().Length - 1));
Sb.Append("}");
return Sb.ToString();
}
else
{
return "0";
}
}
My problem is removing special charters OR How to allow special characters.?
Please help me anybody...
You shouldn't use a StringBuilder to convert an object to a JSON string. Use the JsonConverter class in JayRock JSON library and it takes care of Serialising/Deserialising Json for you (including escaping)
try to use inbuilt json serialization
public static string Serialize<T>(T obj)
{
System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new
System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());
MemoryStream ms = new MemoryStream();
serializer.WriteObject(ms, obj);
string retVal = Encoding.Default.GetString(ms.ToArray());
ms.Dispose();
return retVal;
}
